0.05). All fistulas in two groups showed thrill, except one patient (3.3%) in ulnar-basilic group (primary failure). Hypertension was detected in one patient in Radio-Cephalic group, moreover, hematoma was observed in two patients in ulnar-basilic and in two patients in Radio-Cephalic groups and thrombosis was observed in two patients in ulnar-basilic and in a single patient in Radio-Cephalic groups. The aneurism was observed in three patients (10%) in ulnar-basilic and in four patients in Radio-Cephalic fistulas. The steal syndrome was observed in two patients in Radio-Cephalic group, infection in one patient (3.3%) in ulnar-basilic fistulas group and in four patients (13.3%) in Radio-Cephalic group. Conclusions: Fistula patency rates were comparable in both ulnar-basilic and Radio-Cephalic groups and there is no significant evidence of postoperative complication difference between two groups.]]>
